I’m interested in finding out how this works as well. I don’t share a game but have several families I rotate around with. I usually change my family at 6am on a Sunday morning to try and avoid sims being late for work/school. I’ve seen a few comments on another thread but they didn’t really make much sense to me.
I understand that if your sim is at uni when you rotate away they will continue to ‘go to class’ and you will only get the bare minimum reward from that enrolled term. So from what I was previously reading you need to complete your rotation with the sim whose enrolled at university for the whole term and then swap to a different household before you re enrol to stop this from happening.
